GIS Infrastructure in Japan — Developments and Algorithmic Researches
نویسندگان
چکیده
Some activities of geographical data maintenance and standardization work in GIS infrastructures in Japan are first reviewed. Then, from the viewpoint of geometric and combinatorial algorithmics, applied aspects of GIS are described. Some spatial data mining technique is mentioned first, and then the problem of inferring topological information from digital map and the label placement problem are touched upon. As one of topics in ITS (Intelligent Transport System), finding useful detours in car navigation is discussed. These would illustrate some advanced aspects of GIS infrastructure and its high-level use in Japan.
